Sea Otter: Shimano Deore XT M8000 11-Speed
Shimano trickles down 11-speed to XT but adds the hallowed 42-tooth cog

By Francis Cebedo April 24, 2015 COMPONENTS SEA OTTER CLASSIC
2015 Sea Otter Classic

This Santa Cruz Bronson is decked out with the XT M8000 Group

What is it?

Who doesn’t like Shimano XT? Any serious mountain biker has touched XT at one point or another as it was the first dedicated mountain bike group and it has always been the standard for value and performance. XTR is the golden child of Shimano with the latest technology, the lightest weight and the best looks. And there’s always a lag between the launch of the new XTR and the ‘trickle-down’ of this new technology to XT. Well the wait is almost over as the new XT has been introduced at Sea Otter 2015.

More than trickle-down

The good news is since this space is ultra-competitive at the moment, Shimano seized the opportunity to introduce new technology in XT that was not present in the latest XTR. Most notable of which is the introduction of the 11-42T cassette. In addition to the 11-40T, this new 11-42T cassette will complement the XT group for 1×11 setups. This cassette can be used in existing 11 speed XTR setups as well. The spacing between the cogs will not be as close as the 11-40 but the presence of the 42T cog is critical for achieving a proper low gear in a 1×11 setup. The 11-42T is not approved for 2×11 use but we don’t know at the moment if it will not work or it is merely not advised for optimal operation.

XT M8000 Rear Derailleur

There are now two options for the rear cassette, 11-40 and 11-42 (click to enlarge).
Quite a looker but no Di2

The new XT group steals the crown from XTR as most desirable looking component group. The cranks look absolutely dialed and the black on black finish is understated and will match any bike.

Di2 is not present on XT at the moment but we fully expect that to be introduced in the future. Since everything on XT is compatible with XTR, one can conceivably purchase the Di2 specific components and match with some XT to lower the cost of entry into Di2.


We haven’t ridden the XT yet but we fully expect it to come very close to matching the performance of XTR just as it’s done so in the last few generations. The main compromise is usually weight. And we’ve been testing the latest 2×11 XTR group and it has been remarkable. Rear shifting is impeccable and front shifting is better than anything we’ve experienced before. With the wider range in the rear, Shimano was able to close the gap between the two front rings and this results in better shifting and less loss of pedaling cadence.

Expanded Rhythm Step gear options

Like its XTR sibling, Deore XT M8000 offers 1×11, 2×11, and 3×11 crank options to satisfy any type of rider ability level or terrain. New 2×11 and 3×11 M8000 drivetrains, expand range while maintaining even better rhythm when paired with an 11-40T cassette for optimized cadence control. An exciting addition for Deore XT M8000 is a 1×11 specific 11-42T cassette that expands Shimano’s 1×11 gear range slightly over the race inspired 11-40T of XTR.

Deore XT cranks Rider Tuned for any terrain

Deore XT M8000 cranks feature Rider Tuned 11-speed gearing that will take you anywhere you want to go. Whatever option you choose, new materials provide consistent long-life shifting performance and chain management.

The Dynamic Chain Engagement (DCE) 1×11 tooth profile in new XTR and DEORE XT groups increases chain retention force by 150%, drastically decreasing dropped chains. Stainless steel chain ring teeth provide long life and lasting chain retention.

All new Deore XT cranks turn on an updated bottom bracket that reduces weight and bearing drag while improving mud durability.

Redesigned, lighter action derailleurs

Both the front and rear Deore XT M8000 derailleurs receive a complete makeover.

Deore XT shifters enhance feel, ergonomics, reduce shift effort

Shimano’s new Deore XT M8000 shifters feature improved ergonomics and longer, textured levers that create an enhanced interface between rider and controls and decrease shift effort. Multi Release shifting increases trail capability while Vivid indexing guarantees shift accuracy.

Industry-standard braking is even better

Deore XT hydraulic disc brakes are the industry benchmark for affordable high performance. With M8000, Shimano retains that standard while upgrading with a new, integrated master cylinder. This gives a sleeker look, saves weight and frees up valuable handlebar space.

Lighter, wider rimmed Deore XT Race and Trail wheels

The WH-M8000-TL-275/29 and WH-M8020-TL-275/29 offer new tubeless-ready aluminum rims in 20mm and 24mm internal width respectively. Each rim provides a wider platform for modern mountain bike tires while also saving 40 grams over previous models. All wheel sets use 28 butted spokes both front and rear.

Deore XT pedals offer wider, redesigned platform

Shimano’s new PD-M8000 Race and PD-M8020 Trail pedals offer legendary SPD performance that improves the rider experience at this vital connection point. With increased stability and contact area over the previous generation, power, control and confidence are improved.

Pricing has not been determined but we expect it to very close to the outgoing XT’s pricing. For more information visit bike.shimano.com.
